Explanation

The 6th period of the modern periodic table contains 32 elements.

This period is known as the "extended" period and includes elements from the Lanthanide series. 

It is the longest period of the periodic table

Explanation

The telencephalon is the part of the developing brain that eventually forms the cerebral hemispheres.

The term "cerebral hemispheres" is synonymous with the telencephalon. 

Explanation

If a codon consisted of only two nucleotides, there would be 16 possible codons. 

Since there are four possible nucleotides (A, C, G, and T), each position in a two-nucleotide codon could be filled by any of these nucleotides.

Therefore, to calculate the total number of possible codons,

We multiply the number of possibilities for the first position by the number of possibilities for the second position:

4 nucleotides * 4 nucleotides = 16 possible codons. 

Explanation

At room temperature, H₂ (hydrogen) has the lowest density among Ne (neon), N₂ (nitrogen), and CO (carbon monoxide). 

Density is directly proportional to molar mass, meaning the gas with the lowest molar mass will have the lowest density.

Hydrogen has the lowest molar mass among the listed gases, making it the least dense. 

Explanation

In the 3d series of the periodic table, melting and boiling points generally increase up to the middle,

Reaching a peak around elements like Chromium (Cr), and then decreasing towards the end of the series, with Zinc (Zn) having the lowest melting point. 

Explanation

Iodine is solid due to its high polarizability. 

Iodine is a solid at room temperature due to the strong intermolecular forces present between its molecules, specifically London dispersion forces

These forces arise from the large size and high polarizability of iodine atoms.

Larger atoms like iodine have more electrons, which are easier to distort, leading to stronger attractive forces between molecules.

This allows iodine molecules to stick together in a solid state

Explanation

nsulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Kinetic energy (K.E) in terms of momentum is given by the formula:

K.E = p² / (2m)

Where:  

- p is momentum  

- m is mass  

Explanation

Explanation

The diagnostic test typically used for rheumatic fever is ASO (Anti-streptolysin O) titer.

Rheumatic fever is an autoimmune inflammatory disease

That can develop after a group A streptococcal infection, such as strep throat. 

The ASO titer measures the antibodies produced in response to a recent streptococcal infection.

Elevated ASO titers indicate recent streptococcal infection and are a key diagnostic marker for rheumatic fever.
